Options for controlling the ENGL INVADER II amp remotely:
3. Two-way footswitch (e.g. ENGL Z-4):
Connect two-way
footswitches to the amp by plugging a stereo ¼ " cord
into jack no. 48.
Functions: Channel switching Up/Down (CH1 < > CH2,
CH3 < > CH4) and CH1 < > CH3, CH2 < > CH4;
see page 21 chapter 48 for more details.
This does not afford direct access to each of the four channels.
As an alternative to a two-way footswitch, you can connect
a MIDI switcher (the ENGL Z11-S.A.C. will do nicely) to
this jack (48) to control the two switching functions.

1. MIDI foot board (for example, the ENGL Z-12 or ENGL Z-15 pictured above):
Connect
the foot board to the amp using a standard 5-pin DIN cable. All 5 terminals of both
connectors must be wired in a 1:1 configuration: MIDI data transmission requires two wires,
and the ENGL MIDI foot board uses two more wires for purposes of power supply.
This combination affords access to all of the amp's 128 MIDI presets.
The Z-15 foot board also lets you control
Amp Mute
via MIDI controller #7, see page 20.

2. ENGL Custom Z-9 Footswitch:
This special foot board connects to the amp
via a ¼” stereo cord plugged into the Serial Amp Port (47) or via a 5-pin DIN cord
plugged into the MIDI In port (44). The former option affords switching access
to channels and two special functions (for example,
High Gain
or
FX Loop I/II
),
the configuration table is shown on page 38. In the latter setup, the Z-9 serves
as a MIDI foot board that accesses the first 10 MIDI presets.
